Sensors

MQ sensors, including the MQ2 sensor, have the capability to detect various gases. The MQ2 sensor is specifically designed to detect combustible gases such as LPG (liquefied petroleum gas), butane, propane, methane, alcohol, hydrogen, and smoke. These gases are commonly found in residential, industrial, and automotive environments. The sensor’s sensitivity and responsiveness enable it to detect even trace amounts of these gases, making it a valuable tool for gas leakage detection, fire detection, and air quality monitoring applications. It takes a short time to heat up in order to work correctly.

The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas.

Product usage tips:

When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Two mounting holes enable easy mounting to surfaces. The board comes with four pins that need to be soldered.

ADC (Analog Digital Converter) is a device that reads analog signals (just like the analogRead () function in Arduino IDE) and converts them into digital signals that can be read by a microcontroller. This breakout is based on the ADS1015 ADC, which reads values in 12-bit resolution, receives a maximum of 3.3V on its inputs and has a total of 4 channels (which can also be used as two differential). Works great with any microcontroller at 5V. It has 2 easyC connectors for easier connection on I2C communication.

Joystick module is well known to all – it is identical to the one found in the PlayStation2 joystick. Whether you are making a game with a microcontroller or want more freedom while navigating a joystick module will come handy.

It reads X and Y position of the joystick knob (used for controlling) and whether the joystick is being pressed down. X and Y values are shown in the form of analog values while reading off if the joystick is pressed or not is shown in the form of digital value (HIGH/LOW; it has pull-up resistor).

A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation. This sensor works on the principle of detecting thermal thermal signals emitted by objects, mainly warm-blooded creatures like humans. The “passive” in the name refers to the fact that the sensor itself does not emit or radiate any energy for detection.

Easily connects to Dasduino/Arduino via digital pin. When it detects movement, it sets the output digital pin to HIGH. The angle that the sensor “sees” is 100 degrees and reaches up to 5 meters. It has a potentiometer for delay (how often to check for movement).

It is often used in a variety of applications, including home security systems, automatic lighting, and energy management, among others.

The hall effect sensor (Hall Effect sensor) will be able to detect the magnetic field in its vicinity thanks to the aforementioned physical law. A magnetic field that can be created by a magnet, a current flowing through a conductor or some third source, the Hall effect sensor will recognize each. This sensor has a programmed threshold at which it will change the state of its output signal, so it is a sensor with a digital output.

This module is a phototransistor that is capable of detecting infrared radiation. Since fire radiates a large number of infrared rays, this sensor will detect them, but this is not its only application. Wherever there are infrared waves, the sensor will detect them (including those from the sun). Using the built-in comparator on its outputs gives either digital (HIGH / LOW) or analog (0V-5V) signals, depending on the intensity of the IR radiation.

Light is one of the most important things in the life of most living beings. Because of this, it is common to work with light sensors when learning about electronics. The simple light sensor features a light-dependent resistor (LDR) and a sensor on a small breakout board for easier connection. As the name suggests, the LDR will change its resistance depending on the amount of light it’s exposed to. The amount of light and resistance are inversely proportional. The more light it’s exposed to, the less resistance it will have. Thus, if there’s more light, the board will have a resistance of a few hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.

The main benefit of this board is ability to give analog and digital output. By setting the potenciometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

The pressure is measured in steps of 1hPa (=0.01hPa =0,01mbar), and 0.1°C for temperature.

Product usage tips:

If there is an error while using the breakout board, see if it’s connected properly. Take a look at the pinout. If everything is properly connected, check if the I2C address of the breakout board is correct prior to programming it. The I2C 7-bit address should be 0x77. If everything is correctly connected and the I2C address is right, look through your code once again. There might be some bugs in the code that are stopping the sensor from working as it should.

BMP180 breakout board works very well in combination with any Dasduino board and OLED I2C 0.96” display breakout board. All of them use easyC so they can be connected in a matter of seconds.

To keep the sensor working for a long while, we would advise you not to use it in extreme conditions. Going over or below the temperature range will surely damage the sensor. Same with the pressure. Keep track of the current going through it. Allowing too high of a current through the breakout board will burn the sensor and render it completely useless.

To connect to our PMS7003 air quality sensor easily, we designed this adapter. It allows you to connect the PMS7003 sensor to breadboard or to connect with cables.

RTC (Real Time Clock) is a device that carefully and precisely tracks time and dates. It is extremely precise, so it is more suitable for long-term time tracking than clocks on microcontrollers. This breakout can work with an extremely low current and thanks to the alarm feature and interrupt pin, it will allow a microcontroller to enter sleep mode until its awaken by this RTC.

It has a built-in battery holder (battery not included) and even if power is lost, real-time tracking won’t be affected.

If you encounter errors when using the breakout board, see if it’s connected properly. First, look at the pinout on the board and your microcontroller. If everything seems OK, look at the connections on the breakout board. If all the wiring is correct, make sure that the breakout board’s I2C address is right. It should be 0x70. Everything as it should be so far? Go through your code again. There might be some bugs that are stopping things from working as expected.

To keep the longevity of the sensor, keep track of the current going through the circuit. Allowing an excessive amount of current to flow through it may cause the sensor to fail. It is not impact-resistant. When dropped from a high distance or at an odd angle, it can break beyond repair.

The Hall effect sensor breakout with analog output is a versatile and reliable sensor module designed to detect and measure magnetic fields. It utilizes the Hall effect principle, where the presence of a magnetic field induces a voltage proportional to the strength and direction of the field.

The analog output allows for precise and real-time monitoring of magnetic field strength. It is commonly used in applications such as position sensing, current sensing, and speed detection.
